Movie boss demanded Butler quit smoking

The retired Warner Bros. president wasn't initially keen on director Zach Snyder's decision to cast Butler as his leading man in the epic 2006 movie, but agreed to meet with the Scot.

Put off by his nicotine breath, Horn insisted the actor could only have the role if he promised to stop smoking.

In an interview with trade publication The Hollywood Reporter, Horn says, "I knew from (previous film) Phantom (of the Opera) that he smoked and I thought I smelled it on him, so I said, 'OK, you can have the part on one condition: You have got to stop smoking.'
